[xwiki-users] Backlinks missing

Hello, I'm having trouble with backlinks after updating to XWiki 1.3m1 from 1.1 (some versions of 1.1 were documented to have broken backlinks, thus the desire to upgrade). Links created while I was running XWiki version 1.1 don't appear as backlinks on the pages those links reference. If I create new links they do show up as backlinks on the referenced pages. NOTE: The missing backlinks weren't present in 1.1 either, but I hoped that updating to 1.3 would make them appear. Does anyone know if a) this is expected or documented behavior, and b) if there's any way to coax a very large number of links created in 1.1 in to appearing as backlinks? I don't look forward to manually destroying and recreating hundreds of links... Thanks, - AW
